WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 270,934, dated January 23, 1883, I Application tiled Mayll, 1882. (No model.) Patented in England June 1l, 1878, No. 2,324.

To all whom it may concern:

Be it known that I, BENJAMIN CROCKER CROSS, ot' Dewsbury, in the county of York, England, have invented certain new and useful Improvements in Self-Acting Trough Water-Closets; and -I do hereby declare the following to be a full, clear, and exact description ofthe invention, reference being had to the accompanying drawings, and to the letters 1o or gures of reference marked thereon, which form a part ot' this specification.

My invention relates to improvements in self-acting trough water-closets in which one or more troughs or basins are used, which are emptied, cleansed, and flushed with water at intervals, as required; and the objects of my improvements are, first, to make the water-4 closets seltacting, so that no manual labor is required, and they rarely need to be visited 2o and examined; second, to use only a limited quantity ot' water, which quantity cannot be altered by the users, so that .waste is rendered impossible; third, to thoroughly iiush the troughs with water every time the apparatus works, so that they are always kept clean and healthy.

The accompanying drawings are in illus tration of my invention, in which Figure l is a vertical section otan entire apparatus havin g 3o three troughs or basins. Fig. 2 is aplan; Fig. 3, a transverse section of the same, and Fig. 4 a detail view.

Similar letters of reference refer to similar parts through the several views.

a a a are the troughs or basins, the lower ends of which open into a pipe common to all.

bis a siphon-pipe, the ends ot' which fit and turn in sockets atff iuethe said trough-pipe and in a descending drain-pipe, respectively,

4o the joints being preferably made sufciently water-tight by short lengths of india-rubber pipe, as shown.

o is a tank attached to and turning with the siphon-pipe b. A cord or wire is attached to the siphon-pipe b, and, passing over a wheel1 d, is attached to a balance-weight, g, by which the siphon-pipe b is kept in a position nearly vertical.

eis a wooden or other foundation for the 5o apparatus, and h is a trapped drain-pipe into the main discharge-pipe.

t' is a water-cistern at ahigher level, and it is a tumbler-cistern turning upon a center, b'it prevented from turning and discharging its contents into the cistern t' by a catch, ,'as shown in Figs. 3 and 4, to which is connected a chain or wire attached at its lower end to a lever turning upon a center upon the foundation e, as shown in Fig. 4. This lever is arranged so that the weight g in its descent operates it and releases the catch l. A siphonpipe, m, is arranged so that its upper end forms a siphon in the cistern t', while its lower end passes into and ushes with water one or more ot' the troughs a.

The action ofthe apparatus is as follows: A small regulated stream of water from a `main or other supply is allowed constantly to run' into the tumbler-cistern k, which, when filled, is prevented by the catch Zfrom discharging its contents into the cistern t'. NVhen the tumbler-cistern 7a is thus full of water the water runs over into the main cistern t' and iills it to the level of the overdow-pipe n, through which the water-then passes and fills the balancetank c through a hole in its top. As soon as a certain quantity ofwater has passed into the tank c its weight exceeds that ot' the weighty and the siphon-pipe b suddenly falls to a horlzontal position, as shown in Fig. 2 and in dotted lines in Fig. 3, and the whole contents of the troughs t a a at once rush into the drain. By the time these troughs are empty the water has tlowed from the cistern c through a small hole at its outer end, and the siphonpipe b being thus lightened the weight g raises it again to its vertical position. As it descends the weight g operates upon the lever, which releases the catch l, and the tumblercistern k falls and discharges its contents into the cistern z', raising the level ofthe water in thelatter above the bend of the siphon-pipe m, through which the water flows, discharging the contents ot the cistern t' into the troughs et c a., which are then again ready for use. The cistern t' holds the quantity ot' water required for the supply ot' the troughs at one time. lVhen the tumbler-cistern k has emptied itself it returns toits original position, where it is retained by the catch l. The frequency with which the series ot' operations described takes place is regulated by the supply of water to the tumbler-sistem k, which can be regulated as desired. o is a ventilating-pipe to the drain.

I claim as my invention and desire to secure by Letters Patent- 1. The combination, in trough Water-closets, of the troughs aa a, with the movable siphonpipe b, balance-tank c, means for intermittently supplying Water to the tank, and supply-pipe m, all substantially as set fort-h, and shown in the drawings.

2. In trough Water-closets, the combination of the troughs ct u a, movable siphon I), and

balance-tank c, with the water-supply Siphonpipe m, oistern i, overflow-pipe n, and tumblereistern L, supported by the catch l, and. lever operated by the Weight g, all substantially as set forth, and shown in the drawings. Y

In testimony WhereofI have signed my name to this specification in the presence oftwo sub- 2o Witnesses: EDMUND EDWARDS,

ARTHUR E. EDWARDS.
